Read before using the profile

  • The two sheets identify TS-RDF8K2 / TS-RDF8W2 and the selected media families. No capabilities are inherited from RDF9, RDF2 or other entries in a comparison chart.
  • Simultaneous operation is unresolved: the sheets disagree about two-card/three-card insertion and include a contrary no-two-card note. Do not infer parallel read/write or aggregate throughput.
  • The USB interface is documented as USB 3.1 Gen 1, but the new profile deliberately omits a typed USB endpoint because the text calls it only micro USB. This omission is not a claim that the device lacks USB.
  • Exact card capacity, operating-system support, physical specimen and sustained transfer still require checking.

Reader-specific limit

RDF8 documentation disagrees about simultaneous insertion: EN_RDF8_PS_1905 allows two cards on page 1 but says simultaneous two-card insertion is unsupported on page 2; Transcend-RDF8 describes three on page 1. This reference leaves concurrent operation unresolved.
